<pre>public class <a href="../../../../../src-html/org/apache/commons/net/bsd/RExecClient.html#line.66">RExecClient</a>
extends <a href="../../../../../org/apache/commons/net/SocketClient.html" title="class in org.apache.commons.net">SocketClient</a></pre>
<div class="block">RExecClient implements the rexec() facility that first appeared in
 4.2BSD Unix.  This class will probably only be of use for connecting
 to Unix systems and only when the rexecd daemon is configured to run,
 which is a rarity these days because of the security risks involved.
 However, rexec() can be very useful for performing administrative tasks
 on a network behind a firewall.
 <p>
 As with virtually all of the client classes in org.apache.commons.net, this
 class derives from SocketClient, inheriting its connection methods.
 The way to use RExecClient is to first connect
 to the server, call the <a href="../../../../../org/apache/commons/net/bsd/RExecClient.html#rexec(java.lang.String, java.lang.String, java.lang.String, boolean)"><code>rexec()</code></a> method, and then
 fetch the connection's input, output, and optionally error streams.
 Interaction with the remote command is controlled entirely through the
 I/O streams.  Once you have finished processing the streams, you should
 invoke <a href="../../../../../org/apache/commons/net/bsd/RExecClient.html#disconnect()"><code>disconnect()</code></a> to clean up properly.
 <p>
 By default the standard output and standard error streams of the
 remote process are transmitted over the same connection, readable
 from the input stream returned by
 <a href="../../../../../org/apache/commons/net/bsd/RExecClient.html#getInputStream()"><code>getInputStream()</code></a>.  However, it is
 possible to tell the rexecd daemon to return the standard error
 stream over a separate connection, readable from the input stream
 returned by <a href="../../../../../org/apache/commons/net/bsd/RExecClient.html#getErrorStream()"><code>getErrorStream()</code></a>.  You
 can specify that a separate connection should be created for standard
 error by setting the boolean <code> separateErrorStream </code>
 parameter of <a href="../../../../../org/apache/commons/net/bsd/RExecClient.html#rexec(java.lang.String, java.lang.String, java.lang.String, boolean)"><code>rexec()</code></a> to <code> true </code>.
 The standard input of the remote process can be written to through
 the output stream returned by
 <a href="../../../../../org/apache/commons/net/bsd/RExecClient.html#getOutputStream()"><code>getOutputSream()</code></a>.

<div class="block">Remotely executes a command through the rexecd daemon on the server
 to which the RExecClient is connected.  After calling this method,
 you may interact with the remote process through its standard input,
 output, and error streams.  You will typically be able to detect
 the termination of the remote process after reaching end of file
 on its standard output (accessible through
 <a href="../../../../../org/apache/commons/net/bsd/RExecClient.html#getInputStream()"><code>getInputStream() </code></a>.    Disconnecting
 from the server or closing the process streams before reaching
 end of file will not necessarily terminate the remote process.
 <p>
 If a separate error stream is requested, the remote server will
 connect to a local socket opened by RExecClient, providing an
 independent stream through which standard error will be transmitted.
 RExecClient will do a simple security check when it accepts a
 connection for this error stream.  If the connection does not originate
 from the remote server, an IOException will be thrown.  This serves as
 a simple protection against possible hijacking of the error stream by
 an attacker monitoring the rexec() negotiation.  You may disable this
 behavior with <a href="../../../../../org/apache/commons/net/bsd/RExecClient.html#setRemoteVerificationEnabled(boolean)"><code>setRemoteVerificationEnabled()</code></a>
